Question

How do I perform pediatric tests with Piano Plus VRA from Inventis?

Answer

Piano Plus VRA is one of the three models of the Inventis top-featured audiometer Piano. This audiometer can perform pure tone audiometry on the youngest patients through two most common approaches: Visual Reinforcement Audiometry (VRA) and Conditioned Play Audiometry (CPA). Figure 1. Depicts the pediatric audiometry test window.

This test performs pure tone audiometry and controls the reinforcements. The reinforcements can be of two types: toys in a darkened box and/or LCD displays showing pictures or animations.

Using the Toys as Reinforcement

In case you want to use the traditional interactive toys as reinforcement, they can be directly connected to the audiometer. The back panel of Piano Plus VRA features three additional outputs (stereo jack ¼”) for controlling up to three toys; the stereo jack cable (included with every toy) also brings a power supply to the toy. The toys are enclosed in a wooden box, with a darkened Plexiglas window; when the toy is activated, the internal LEDs turn on, so that the child can see the plush lighting up. The available toys are Peanuts the Dog and Jack the Donkey.

Using the Displays as Reinforcement

One of the key points of Piano Plus VRA is the ability to use images and animations on up to three LCD displays as reinforcement. The displays are controlled through a computer with multiple video outputs, on which you need to install Maestro software.

The possibility to perform the pure tone audiometry test on the youngest patients using LCD displays as reinforcement is available also in Cello, Inventis PC-based diagnostic audiometer.

The main features of Maestro software for the video-VRA are:

  • Real-time audiogram on the display (“Monitor” function)
  • Selection of the images/animations to be used on the displays and control of the delivery
  • Control of the baby’s feedbacks through a webcam

The displays can be used in connection or in substitution of the traditional toys. Like with the toys, you can configure the system with one, two, or three LCD displays dedicated to the reinforcement (plus one display for the operator).

The webinar delves into the crucial role of gaze stabilization in daily functioning, which allows individuals to track objects, orient in space, and perceive the world in three dimensions. It examines the complex interactions between the brain and peripheral sensors that manage signals sent to oculomotor and spinal muscles, highlighting the vestibular system's key contribution. The session discusses how eye movements reflect brain integration processes, and how abnormalities in these movements can indicate neurological issues, often before they are detectable through imaging. The presentation features a personal collection of over 80 abnormal eye movements to illustrate different neurological pathologies, utilizing advanced computerized tools to measure and diagnose these abnormalities.
